48 Chapter 8. Logical Objects 8.3 Schedules Scheduling is a way to create timing constraints on the firewall's rules. It enables the user to define a certain time period, in the format of year-date-time, wich will only activate the rules at the designated times. Any activities outside of the scheduled time slot will not follow the rules and will therefore likely not be permitted to pass through the firewall. The schedules can be configured to have a start time and stop time, as well as creating different time periods in a day. Example: An office-hour schedule An organization may only want the internal network users to access the Internet during work hours, and expect this constraint to be valid for one year. Therefore, one may create a schedule to restrict the firewall to allow traffic Monday-Friday, 8AM-5PM only, starting from a certain date and time, say 2005-04-01 00:00:00, to an end date. During the non-work hours, the firewall will not allow the access. WebUI : Objects → Schedule Profiles → Add → Schedule Profile: General Name: Enter a name for this schedule, e.g. "office-hour". Define a time period by checking the boxes. Start Date: Fill in the start time in a format of "yyyy-mm-dd hh:mm:ss" or click the calendar icon and choose a date from the pop-up window. End Date: (same as "Start Date" above) and then click OK. D-Link Firewalls User's Guide
